Retinoblastoma(RB)is the most common intraocular malignancy of children with extremely poor prognosis. MicroRNAs are small non-coding single-stranded RNAs in eukaryotic cells, which regulate the expression of gene by mRNA degradation or translation inhibition. MicroRNAs, acting as oncogenes or tumor suppressor genes, are associated with the occurrence and development of RB directly, which is vital for the early diagnosis and clinical targeted therapy of RB. This review summarized the expression of microRNAs in RB and the related mechanism.

Objective To study the protective effect of total flavones of hawthorn leaf (TFHL) on renal ischemia/reperfusion (I/R) in rats.Methods A model of renal I/R was made by clamping double renal pedical for 60 min and reperfusion for 24 h.TFHL (30 or 60 mg/kg) was injected before clamping renal ischemia. The level of serum urea nitrogen(BUN), serum creatinine(Scr), tumor necrosis factor-?(TNF-?),interleukin-1(IL-1) in serum were detected after reperfusion for 1 and 24 h,respectively,and the level of malonaldehyde (MDA) and erythrocuprein (SOD) in renal tissues were measured after reperfusion for 24 h.Results TFHL significantly decreased the level of BUN and Scr, decreased the concentration of TNF-? and IL-1 in serum. Pretreatment with TFHL also enhanced the activity of SOD reduced the concentration of MDA in renal after I/R.Conclusions TFHL has significantly protective effect on renal I/R and markedly improve the renal function. The mec-hanisms are associated with decreasing the lipid peroxidation reaction and reducing the level of TNF-? and IL-1.

?AIM:To observe the values and changing rules of angle Kappa in corneal refractive surgery under light and dark conditions.?METHODS:Two hundred and thirty-four eyes of 118 patients for corneal refractive surgery were enrolled for this study.Pupil diameters and angle Kappa values under light and dark conditions were measured by Keratron Scout corneal topography.?RESULTS: There were significant differences in pupil diameters between light and dark conditions (P<0.01). More angle Kappa of both eyes distributed in the superior nasal quadrant under light conditions, and more angle Kappa distributed in the superior temporal quadrant under dark conditions.The differences of horizontal and vertical offsets of angle Kappa under two conditions were statistically significant (P<0.01).?CONCLUSION: The changes of pupil diameters in light and dark conditions could affect angle Kappa and then affect the accuracy of corneal refractive surgery centered on angle Kappa.

Objective To study the interobserver variabilities and the differential diagnosis value of Breast Imaging Reporting and Data System-Ultrasound (BI-RADS-US) lexicon for small ( ≤ 2 cm) breast nodules. Methods Between January 2009 and December 2011, 289 patients with small (≤2 cm) breast nodules (n=317) were included. According to sizes, the lesions were divided into two groups, i.e., 0-1 cm (n=160) group and 1-2 cm (n=157)group. Each lesion was described independently by 3 radiologists using BI-RADS-US lexicon. Interobserver variabilities were assessed by Kappa test. Chi-square test was used to compare the frequency difference of the descriptors between malignant and benign lesions. Sensitivity, speciifcity, accuracy, positive predictive value and negtive predictive value were calculated. Results (1)Moderate agreements were obtained for lesion shape, orientation, margin, echo pattern, surrounding tissue and calciifcations (κ=0.44, 0.57, 0.48, 0.43, 0.51 and 0.57) in 0-1 cm group. Substantial agreements were obtained for lesion shape, orientation, margin and echo pattern (κ=0.65, 0.61, 0.64 and 0.63) in 1-2 cm group. (2)Irregular shape, non-parallel orientation, non-circumscribed margin, echogenic halo and microcalciifcations were more frequently found in malignant nodules than in benign nodules in 0-1 cm group [52.3% (34/65) vs 20.0% (19/95), 38.5%(25/65) vs 13.7%(13/95), 75.4%(49/65) vs 32.6%(31/95), 18.6%(12/65) vs 0 (0/95) and 10.8%(7/65) vs 2.1%(2/95);χ2=18.19, 13.08, 28.22, 16.39 and 3.95;P=0.000, 0.000, 0.000, 0.000 and 0.047]. Similarly, irregular shape, non-parallel orientation, non-circumscribed margin, echogenic halo, shadowing, changes of Cooper′s ligament and microcalciifcations were signiifcantly more frequent found in malignant nodules than in benign nodules in 1-2 cm group [74.2%(49/66) vs 12.1%(11/91), 36.3%(24/66) vs 5.5%(5/91), 93.9%(62/66) vs 22.0%(20/91), 37.9%(25/66) vs 3.3%(3/91), 30.3%(20/66) vs 7.7%(7/91), 15.2%(10/66) vs 0 (0/91) and 16.7%(11/66) vs 4.4%(4/91);χ2=62.59, 24.21, 79.40, 31.22, 13.73, 12.30 and 6.67;P=0.000, 0.000, 0.000, 0.000, 0.000, 0.000 and 0.010]. (3)In both groups, a good sensitivity was demonstrated (75.4%&93.9%) when using the non-circumscribed margin as a criterion for malignancy, and high speciifcity was achieved in two groups (80.0%-100%and 87.9%-100%) when other descriptors including irregular shape, non-parallel orientation, echogenic halo, shadowing, changes of Cooper′s ligament and microcalciifcations were used as differentiation criteria. Conclusions Good interobserver agreement can be achieved using the BI-RADS-US lexicon in the diagnosis of small breast nodules. Non-circumscribed margin are proved as the most valuable sign for screening malignant breast lesions ≤ 2 cm. High speciifcity was found for irregular shape, nonparallel orientation, echogenic halo, shadowing, Cooper′s ligament changes and microcalciifcations, which can help biopsy and preoperative diagnosis.

BACKGROUND: Coronary artery disease (CAD) risk in type Ⅱ diabetics is one of the hot topics in clinical research.OBJECTIVE: By using electron-beam tomography(EBT) technology, heart scans were performed to investigate coronary artery lesion in type Ⅱ diabetics and their CAD risks were evaluated as well.DESIGN: Comparative study based on type Ⅱ diabetics complicated with coronary artery lesion.SETTING: Gerontology department in a hospital affiliated to a military medical university of Chinese PLA.PARTICIPANTS: From January 2002 to June 2004, 93 inpatients between the ages of 36 and 78 in the Gerontology Department of Xijing Hospital, an affiliation to the Fourth Military Medical University of Chinese PLA, were selected(male 80, female 13) . Totally 25 of all the patients proved normal by physical examinations were set as normal control(male 22, female 3) group; other inpatients were divided into the abnormal blood glucose group and the coronary heart disease (CHD) group respectively according to their examination results. Of the 57 patients in the abnormal blood glucose group,49 were male and 8 were female. This group was divided into two subgroups:the impaired glucose tolerance group(IGT) containing 29 patients and the diabetes group containing 28 patients. In this group, 44 patients have had heart symptom of different extent. Of the 11 patients in the CHD group, 9 were male and 2 were female. Inclusion criteria: patients with type Ⅱ diabetes were defined by American Diabetes Association in 1979; patients with CHD were defined in the report of the Joint International Society and Federation of Cardiology/World Health Organization Task Force on the standardization of clinical nomenclature and criteria for diagnosis of ischemic heart disease in 1979, and they were all confirmed by coronary angiography. Exclusion criteeases.METHODS: Both plain EBT heart scanning and contrast-enhanced heart scanning were performed on the 93 patients to evaluate the occurrence of coronary artery calcification(CAC), the number of stenosed coronary arterie,and the number of soft plaques. Additionally, other examination results including blood glucose, blood HbA1c and blood lipid were also collected for comparison between the conditions of coronary artery and assessment of the CHD risk among groups.MAIN OUTCOME MEASUREMENTS: In all the groups, the occurrence of CAC, the number of stenosed coronary arteries and the number of plaques were compared, and the CHD risk was analyzed.RESULTS: The occurrence of coronary artery calcification was significantly increased in all the study groups as compared with the control group(x2 = 18.88, P < 0. 01 ). Increasing trend was also observed in the study groups when calculating the number of branches with coronary stenosis and plaques ( F = 10. 758, P < 0. 01; F = 9. 991, P < 0.01 ). CHD risk in diabetes was estimated to be 7. 514 (95% confidence interval, 1. 885 -63. 778).CONCLUSION: Coronary artery lesion can be easily observed in type Ⅱ diabetics,and high CHD risk is predicted in this population. Early diagnosis of CAD and early rehabilitation intervention in grade 2 are extremely important in improving the quality of life and reducing the disability ratio of type Ⅱ diabetics.Huang C, Gao JY, Wong XM, Li R, Yang AL, Zheng MW, Xue FB.
